Gotham: Robin's Parents are Coming, But No Harley Quinn (Yet)

Those hoping for a Harleen Quinzel / Harley Quinn appearance on Gotham will have to wait a little longer, but a "prenatal origin story for Robin" is definitely in the works.

Gotham star Ben McKenzie, who plays James Gordon, first hinted that The Graysons might make a cameo. Now, Gotham showrunner Bruno Heller confirmed to EW that the series has "an episode coming up where we learn how Robin’s parents got together."

However, despite the rumors, don't hold out for a Harley Quinn role—at least for now. "We haven’t got Harley Quinn in it," Heller said. "Riddler’s girlfriend is coming up. And Harley Quinn is definitely planned for later on, but so far no.

"You can’t just keep pumping these characters into the show in a comic book sort of way, because you get the Super Friends effect—which isn’t a bad effect, but then you have spaceships and need to go underwater and get wacky villains and the rest of it,” he said. “You have to work as a character piece first. First it has to be real.”
